I need serious help to fix my GPS. I want to follow the steps, but all the links are dead. So I have no idea how to obtain 10.1 or original stock firmware to fix gps.

Anyone can help with the files?
I managed to get the necessary stuff, shortly before Thanksgiving. I was away for the holidays, so I haven't tried it yet. I'll see if I can find the links that I used, and if they've died already we can figure something else out.

Thanks for trying to help. :)

    I hope this will work for you. This worked for me. I don't pretend to understand all the details of what went wrong, but from what I understand there's a non-volatile (ie factory reset, reboot, etc won't fix it) privacy setting on the GPS which, when activated, basically breaks GPS. Samsung must have realized this was stupid too because the latest stock rom/modem doesn't mess with this setting anymore. Unfortunately, if it was set before you upgraded to the newest modem, that means your GPS is stuck in privacy, aka non-working mode (stupid because if you didn't want GPS you should just turn it off).

    So what you need to do is backtrack to a combination of software that DOES mess with this setting. Once you are SURE GPS is working again, you can consider flashing the new stuff again (you may have to try more than once because there is absolutely no user control of the privacy setting, another stupidity in the system).
    So
    1. Flash either an older stock image (newer stock image contains the same privacy bug so you can't use that) or older cyanogenmod and modem. For stock, I recommend the original firmware released with the phone https://dl.dropboxusercontent.com/u/103520801/T699UVALH1_T699TMBALH1_T699UVALH1_HOME.tar.rar
    That is what fixed mine
    You can try the following version of cyanogenmod + modem

    2. Do a battery pull and wait a minute. Just to clear out anything that might be lingering.
    3. Obtain a solid GPS fix. Install GPS Status and stand outside. If GPS doesn't come back at this point try the other route (cyanogenmod or stock)
    4. Turn off GPS.
    5. Battery pull, do not power off
    6. Flash forward to cyanogenmod (build 111 or higher)/newer modem. You can try restoring your nandroid (at this point mine worked with a restored nandroid) but if GPS goes away again try with a fresh install.
    7. If you obtained GPS on stock but cannot get GPS going in cyanogenmod try repeating again but replace step 4 with "do battery pull while you have a solid gps fix"

    Hi,

    All of the original firmware files seem to be MIA. Does anyone have an alternative link to the original modem?

    Thanks

    Found it here...

    Worked perfectly.

    1. Backup CM11.
    2. Wipe all partitions.
    3. Flash CM10.1 and Modem.
    4 Pull battery.
    5 Boot CM and install Google Maps
    6. Set GPS to device only and open G Maps
    7. GPS WORKS!
    8. Reboot to recovery (forgot to disable gps)
    9. Wipe partitions and restore CM11 backup
    10. GPS WORKS!

    I am however on baseband T699UVLJ1 and I believe T699UVBMC5 is the latest one.
    All seems to be working so I will leave it like this for a day and then update and test GPS again.

    Flashed to the latest baseband again without any problems so far
